Fairness in Automatic Speech Recognition Isn’t a One-Size-Fits-All (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Pre-trained speech models like Whisper exhibit inconsistent group-level performance that varies across domains. |
| Approach: | They fine-tune a Whisper model on the Fair-Speech corpus using basic fine- tuning, demographic rebalancing, gender-swapped data augmentation and a novel contrastive learning objective. |
| Outcome: | The proposed method achieves stable, cross-domain fairness improvements without changes to the training data distribution and with minimal accuracy trade-offs. |
